# Crypto calls and puts: a right, a premium and a payoff

A call gives its buyer a contractual right tied to buying the underlying at a strike price; a put gives a right tied to selling. The buyer pays a premium, while the seller assumes the corresponding obligation. Crypto options can settle a cash-equivalent payoff instead of transferring the underlying, so exercise style and settlement specifications matter.

## Key facts

- **Call:** A call’s expiry payoff benefits from prices above its strike. ([What is an Option?](https://www.optionseducation.org/optionsoverview/what-is-an-option))
- **Put:** A put’s expiry payoff benefits from prices below its strike. ([What is an Option?](https://www.optionseducation.org/optionsoverview/what-is-an-option))
- **Expiry:** European-style options exercise only at expiry. ([Inverse Options](https://support.deribit.com/api/v2/help_center/en-us/articles/31424939096093.json))

## Separate payoff from profit

Imagine a one-unit, quote-currency-settled call with strike 100 and premium 8. At expiry with a settlement price of 120, gross payoff is 20 and profit before fees is 12. At 105, gross payoff is 5 but the buyer loses 3 after the premium.

For a put with strike 100, a settlement price of 80 gives a gross payoff of 20. These simplified linear examples are not the settlement calculation for every crypto option.

## Buying and writing have different obligations

A buyer can lose the premium if the option expires worthless. A seller receiving that premium has taken an obligation whose loss can exceed the premium, with collateral and liquidation rules set by the venue. Selling an already-owned option to close is different from writing a new short option.

## Read the specification before the ticker

Check underlying, multiplier, strike, expiry, exercise style and settlement currency. Deribit’s cited inverse options are European and settle economically in BTC or ETH; a familiar call/put name does not make the contract physically deliver spot tokens to a wallet.

## Questions

### Does in-the-money mean my purchase was profitable?

No. The payoff must also cover the premium and applicable costs.
